Well, this is certainly not depressing!

Scientists have found the brain's 'misery molecule' believed to be responsible for all of our feelings of stress and anxiety. Researchers believe that the protein - named CRF1 - could also be linked to depression.

And with the rise of drug targeting medical technologies, researchers hope they can develop specific drugs that will target the protein molecule and, thus, reduce depression in patients. (HT: DrudgeReports)
